Handle IPv6 addresses in full_uri (add brackets)

[wvu]

We're not ready for IPv6.

• use auxiliary/scanner/http/ms15_034_http_sys_memory_dump
• set rhost to an IPv6 address
• Ensure a web server is running on the address and port specified
• Make sure you don't receive a URI::InvalidURIError from missing brackets

Release Notes

This adds brackets around IPv6 addresses in generated HTTP URIs. Some modules like auxiliary/scanner/http/ms15_034_http_sys_memory_dump would previously crash or produce invalid URIs as output when run against IPv6 hosts.
